One of the most fundamental questions in biology is how a single fertilized egg produces the diverse cell types making up the body – from neurons and skin to muscle and blood – that bear the same ...

The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that plays a key role in this protection is the microfold cell (M cell). These ...

How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...

In the tiny, beaded chain of the cyanobacterium Anabaena sp. ATCC 33047, two different cells, the photosynthetic factory worker and the nitrogen-fixing specialist, play distinct and powerful roles in ...

An international group of researchers has identified an important mechanism that enables stem cells to evade immune rejection. Their research, published in Nature, sheds light on how these specialized ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

The immune system is comprised of two separate active arms of immunity to provide robust protection against disease. The two separate systems of immunity include the innate and adaptive immune ...

When we hear sounds, specialized cells in the cochlear nucleus are the first to process that information, enabling our brains to understand speech, enjoy music and recognize various noises. For ...

Researchers at the University of British Columbia (UBC) have made a significant discovery regarding the cultivation of specialized immune cells, which facilitates the development of readily available, ...

New findings reveal that obesity significantly impaired the quality and longevity of antibody responses to a Pseudomonas aeruginosa vaccine in a mouse model. The impaired antibody production was due ...

Banding patterns of cellulose increase the stability of plant cell walls, much like the corrugated patterns in cardboard. Penn State biologists developed a method to isolate plant cells and observe ...

An international group of researchers led by Kazuhiro Furuhashi (Nagoya University and Columbia University) and Joji Fujisaki (Harvard University and Columbia University) has identified an important ...
